Video above is a T16 phoenix map, skipped the expedition so you didn't have to see me place barrels.
Love this build, and I almost always dislike builds like this.
The damage is nice, it's very consistent, it's relatively safe, and above all else it's comfortable. I value comfort over everything. The clear is also way way better than everyone said it would be when I mentioned building it. Not the fastest, but absolutely far from the slowest.
Starting off with it (swapped from Helix around level 70 to HoAg) the damage was more than enough for early maps, all I really needed was some pure agony medium clusters.
The investment path is very very straightforward, i.e upgrading to 7p voices for more pure agony, then getting 2 damage+reservation circles, then chest, blah blah.
Highest end damage can come from around the 10ex investment, and every investment from then on works towards making the build more and more defensive/comfortable.
Worth noting before I talk about spending on this build: 7p voices are 100% serviceable and you only lose like.. two 5% life nodes total by using 2x 7p instead of 2x 5p. The power gap between each 5p and 7p is a single point. Also a lion's share of the cost would come from empower 4, but 3 is cheap and also 100% serviceable.
Excluding Empower 4 (lucky corrupt), overall I've spent roughly 20-25ex on all the gear, including 5p voices, and some of it is very specific with regards to a lucky glorious vanity. Maw of Conquest is what really strains the build's suffix requirements, but when you find yourself able to fit it in, it's such a lovely qol since you stop damaging yourself.

Note that 70 virulence is pretty consistent with lancing steel, so it's set like that in pob.
Let me know if you want more info or have any suggestions.
